How many fishes are in the world 2022?
According to FishBase about 34,800 species of fish had been described as of February 2022, which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds.
Overfishing statistics: The trends are clear
Nearly 80% of the world's fisheries that are already fully exploited, over-exploited, depleted, or in a state of collapse. Worldwide, 90% of the stocks of large predatory fish, such as sharks, tuna, marlin, and swordfish, are already gone!
The world will be able to catch an additional 10 million metric tons of fish in 2050 if management stays as effective as it is today, says the report. But increasing catches without significantly improving management risks the health of predator species and could destabilize entire ecosystems.
Some estimates report the world's oceans are home to 20,000 species of fish. Ocean fishes come in all shapes, sizes, colors and live in drastically different depths and temperatures.
Global fish production
Not only has the world population more than doubled over this period, the average person now eats almost twice as much seafood as half a century ago.
The Ellen MacArthur Foundation's updated figure for fish in the sea in 2050 is roughly 899 million tonnes.
It is unlikely that the oceans will be empty of fish by 2048. Although experts disagreed on the effectiveness of the Seaspiracy documentary to help protect the oceans, they all agreed that overfishing is a major issue.
While the oceans aren't in danger of drying out in the near future, the animation is reminiscent of what the Earth may eventually look like, if CO 2 levels continue to rise. High atmospheric CO 2 in the range of 4,500 to 6,000 parts per million could lead to the evaporation of the Earth's ocean over time.
Fish and other aquatic species using creeks, streams and rivers to roam, eat and reproduce often find their way blocked by dams, as well as roads and rail crossings. The presence of barriers such as dams can impact fish migration.
Paul Watson: The reality is that if the ocean dies, we die – because the ocean provides all of those things which make it possible for us to live on the planet. Over 70% of the oxygen is actually produced by phytoplankton in the ocean, and since the 1950 there's been a 40% diminishment in phytoplankton population.
What happens if fish go extinct?
A world without fish is a scary prospect. Without them, life as we know it will not be possible. The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources.
The oceans, however, are also a crucial part of the planet's water cycle, which in turn drives the weather and climate. With only meagre amounts of fresh water on the Earth, our fertile little blue marble would quickly dry out. See just how difficult life might become by watching the video above.
The Sargasso Sea is a vast patch of ocean named for a genus of free-floating seaweed called Sargassum.
Aside for some microorganisms and algae, this salt water lake is completely devoid of life. There's no seaweed, fish or any other creatures found in or around its turquoise waters.
Seaspiracy claims fishing catches up to 2.7 trillion fish per year, or 5,000,000 every single minute, and says that no industry on earth has killed as many mammals.
Thousands of years ago, First Nations and Inuit were already fishing with nets, hooks, and longlines as well as spears and traps, to catch species ranging from shrimp to whales. Native people gained deep knowledge of fish growth and migrations.
Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 percent, according to a study by the WWF and the Zoological Society of London (ZSL).
Scientists believe that Methuselah, an Australian lungfish, is about 90 years old.

A study from an international team of ecologists and economists have predicted that by 2048 we could see completely fishless oceans. The cause: disappearance of species due to overfishing, pollution, habitat loss and climate change.
What will our oceans be like in 20 years?
Experts say 90% of coral reefs could soon be dead, waves of mass marine extinction may be unleashed & seas may be left overheated, acidified and lacking oxygen.
We all rely on the ocean, whether we know it or not. Earth's vast expanses of water are key to the success of all life on Earth. We eat fish from the ocean, we breathe the oxygen it gives off, we feel the warmth of its huge currents. Without a healthy ocean, humans cannot thrive.
You might be surprised to learn that, no, they don't. At least, not as far as we know. Based on everything we know about goldfish, it is very unlikely that goldfish feel loneliness. It's normal to wonder whether your goldfish will get lonely if kept in a tank on their own.
The oceans cover 70% of the world's surface, and despite what you have seen on nature documentaries, most of the ocean is empty, dark, cold, and void of mammalian life. However, unlike the land, the ocean exists in three dimensions.
Our Sun is middle-aged, with about five billion years left in its lifespan. However, it's expected to go through some changes as it gets older, as we all do — and these changes will affect our planet.
Ocean water freezes at a lower temperature than freshwater.
At least 15 percent of the ocean is covered by sea ice some part of the year. Ocean water freezes just like freshwater, but at lower temperatures.
on the other hand, numerous and heavily populated sinking cities like mumbai, shanghai, nyc, and miami are at risk. 'with a population of 10 million, jakarta is considered by some to be the fastest-sinking city in the world and is projected to be entirely underwater by 2050.
But for now, as far as scientists understand it, sharks and other fish aren't capable of smiling. That's despite the fact that some really look as if they're smiling.
The cerebral cortex and limbic system are absent in fish. Cerebral cortex, which is what permits other animals to cry. Tear ducts are present in both fish and aquatic mammals like whales and dolphins. This is because the eyes of these animals are perpetually wet from their aquatic environment.
The number one killer of pet fish…
What is this? Stress! It isn't good for humans, and it definitely isn't good for fish. Stress on fish eventually result in its death.
Are we killing the ocean?
Human activities are threatening the health of the world's oceans. More than 80 percent of marine pollution comes from land-based activities. From coral bleaching to sea level rise, entire marine ecosystems are rapidly changing.
In the water of the Dead Sea, there's less sodium chloride and more of other kinds of salts. WHY CAN'T YOU SINK IN THE DEAD SEA? The water of the Dead Sea is full of salt, which makes it much denser and heavier than freshwater. If you swim in it, you float very easily.
Cold water also encourages the formation of adipocere. This is a waxy, soapy substance formed from the fat in the body that partially protects the body against decomposition. Bodies have been retrieved almost completely intact from waters below 7°C after several weeks, and as recognisable skeletons after five years.

“By 2050, moderate flooding — which is typically disruptive and damaging by today's weather, sea level and infrastructure standards — is expected to occur more than 10 times as often as it does today,” said Nicole LeBoeuf, NOAA National Ocean Service Director.
Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
It is estimated oceans hold about 97.5% of the total water available on the earth. While the oceans constantly lose water through evaporation by sunlight and wind, at the same time they receive water through rivers, underground channels and rainfall.
According to a paper entitled Plastic Pollution in the World's Ocean, the South Atlantic Ocean is the cleanest. The South Pacific is the least polluted of the world's oceans.
What is the richest sea?
San Pedro Martir – Sea of Cortez is the richest body of water on our entire planet. The Island of San Pedro Mártir is located in the Gulf of California right in the limit between the Northern and Central Gulf Regions.
Drinking seawater can be deadly to humans.
Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.
Beginning in the 1960s, however, Israel and Jordan began diverting much of the Jordan River's flow and increased the use of the lake's water itself for commercial purposes. The result of those activities was a precipitous drop in the Dead Sea's water level.
The Dead Sea is the lowest point on Earth at about 1,400 feet (430 metres) below sea level. Its waters are 10 times saltier than regular sea water. While full of therapeutic minerals, the water is toxic to ingest.
“Fish do feel pain. It's likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
Fish have nerves, just like cats, dogs, and humans, so they can feel pain. Hooked fish endure not only physical pain but also terror. When they're removed from their natural environment, they start to suffocate. Just imagine the horrible feeling you'd experience if you were trapped underwater.
Researchers find that wild cleaner fishes can remember being caught up to 11 months after the fact, and actively try to avoid getting caught again.
The total number of living fish species—about 32,000— is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined.
Known by the scientific name Cirrhilabrus finifenmaa, the colourful fish was found at depths ranging from 131 to 229 feet (40 to 70 metres) beneath the ocean's surface off the Maldives.
How many animals are there in the world in 2022?
In 2022 it listed 2.16 million species on the planet. In the chart we see the breakdown across a range of taxonomic groups – 1.05 million insects; over 11,000 birds; over 11,000 reptiles; and over 6,000 mammals.
numbers of fish caught
It is estimated that 0.97-2.7 trillion wild fish are caught globally each year. Recognising the limitations of the fish size data available, it is concluded that the number of fish caught is of the order of a trillion.
The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000. Counting the number of fish is a daunting and near-impossible task. The number is also constantly changing due to factors such as predation, fishing, reproduction, and environmental state.
The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources. The effects of a world without fish in the sea would be felt by everyone.
There are 64 extinct species, 85 possibly extinct species, and six extinct in the wild species of ray-finned fish evaluated by the IUCN.
The biggest fish in the ocean is the Rhincodon typus or whale shark. Despite their tremendous size and intimidating appearance, whale sharks are commonly docile and approachable.
Its best outcome was the discovery of a jellyfish species new to science. The researchers named it Carybdea wayamba, in honor of the university.
There may be a dozen or so left that as yet are unknown to science. Most of the fish and reptiles are already identified, but there remain several thousand more left to find. Meanwhile, new techniques in molecular biology are helping scientists identify new amphibian species.
The study evaluated 15,484 species of birds and land mammals on body mass, diet, number of offspring, breadth of habitat, and generation length, according to a statement. Simulations used in the study showed that the average body mass of mammals will fall an estimated 25% in the next 100 years.
They identified that over 17,000 species will lose some of their habitat by 2050, with over 1250 species losing 25 per cent and at least 350 species projected to lose more than half. Worst affected were sub-Saharan Africa and the Atlantic rainforest of Brazil, but losses affected every continent.
What is the newest animal on Earth 2022?
A resplendent rainbow fish, a frog that looks like chocolate, a Thai tarantula, an anemone that rides on a back of a hermit crab, and the world's largest waterlily are among the new species named by science in 2022. Scientists estimate that only 10% of all the species on the planet have been described.
The Highest Death Toll
We kill roughly 1 trillion to 2.8 trillion fish every year—whether for direct consumption from aquafarms, or those caught in the wild to feed the farmed fish we eat. Take a moment to re-read the profound difference between billion and trillion.
Illegal, unreported and unregulated fishing — or IUU fishing — accounts for one of every five wild-caught fish. Some experts estimate that 10–26 million tons of IUU-caught fish is taken each year — an amount equal to 11–19 percent of the global reported catch.
